IMPROVEMENT IN WAGON AXLE-TREES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, CORNELIUS L. CAMPBELL, of Binghamton, in the county of Broou e, and State of New York, have invented a new and improved Mode of Making Skcins or Thimbles for ll'agon Axle-Trees; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a perspective view of my improvement.

Figure 2 is a longitudinal section showing the inside of my improved skein; and

Figure 3 represents the manner of constructing the ordinary skein now in use.

The nature of my improvement consists in the construction of a skcin for wagorraxlc-trecs that can be more easily manufactured and fitted to the axle-spindle, thereby securing more strength of timber without adding to the usual lateral thickness of the shaft or otherwise materially increasing its dimensions.

I construct my improvement of the same material of which the conimon skein is manufactured; but in order to obviate the inconvenience. of the shoulder on the inside of the ordinary skcin I make my improvement of the same angle from end to end, as represented in fig. 2. By this means I use one-half of an inch more timber without necessarily increasing the size of the spindle, consequently increasing its strength.- For the purpose, however, of giving said spindle still more strength I slightly increase the size of the skein, and depress its sides G G at the large end. The inside of said depressions has two plane snrl'nces of the same distance apart as the thickness of the axle-shaft. The ordinary shaft is generally made four inches wide and three and three-quartprs of an inch thick. The inside of the large end of the ordinary skein is made round, audit titted loosely and the smaller and outer end closely, the spindle would be likely to he twisted ofi', particularly if the boxes in the hub were too tight or not properly lubricated. I obviate that difiiculty byvthe depressions G G.

My improved skein is more readily fitted to the spindle than those in ordinary use, as it is only necessary to get the proper angle and size, and the ivork is accomplished at once by means of my patent improved mode of fitting skeins to axletree spindles, or by the ordinary process of dressing it off by the drawing-shave and file.

What I claim, and desire to secure by Letters Patent, is-

Making the skcin of the same angle from end to end, in combination with the depressions G Gonthc large end or shank of theskein, substantially in the manner and for the purpose herein described.
